At initialization, you would want the card to ‘own’ all the receive buffers so it can write new packets into them that it receives, then flip ownership to the driver , and the driver to ‘own’ all the transmit buffers so it can write packets to be transmitted, then flip ownership to the driver. This section possibly contains original research. Please enter a title. If this is cleared, it means the driver ‘owns’ that particular ring buffer entry. The card uses two ring buffers to store packets:

Transmit interrupt mask – if set then an interrupt won’t be triggered when a packet has completed sending. This means you should be able use the original bit software on these members of the PCnet family pcnett single-chip Ethernet controllers.
You can do this by either waiting for an interrupt if you didn’t disable the initialization done interrupt in CSR3 or by polling until CSR0 bit 8 is set. The card maintains separate pointers internally.

I did so and everything went smoothly and I can boot it as a virtual machine – and installed vmtools – but there is no AMD PCnet Ethernet adapter present.

Correct Answers – 10 points. I was struggling for this issue since weeks.

Archived from the original PDF on We will flesh out the interrupt handler later, but you should install the interrupt handler here as otherwise you will get crashes due to unhandled interrupts. Depending on your design this may be preferable.
Please enter a title. You need to parse ACPI tables etc. Interrupt done mask – if set then you won’t get an interrupt when the card has finished initializing. If it is set, it means the card owns it and the driver should amc touch the entire entry.
If a new packet has been signalled then CSR0 bit 10 will be set.
Given that the MMIO access is sometimes absent on emulators or certain systems, this article will focus on the IO port access. Receiving packets is normally done in your interrupt handler – the card will signal an interrupt whenever it receives a packet and has written it to the receive buffer. It has built-in support for CRC checks and can automatically pad short packets to the minimum Ethernet length.

About This site Joining Editing help Recent changes. The card regularly scans all the transmit buffers looking for one it hasn’t sent, and then will transmit those it finds. I was hoping that installing vmtools would automatically create the virtual PCnet ethernet adapter.
However – you gave me an idea – to try to find the driver files in the vmware vmtools install. The next section will enable some interrupts on the card.

I have an old Windows NT4 partition that I wanted to set up as a virtual machine. There are two ways of setting up the card registers: Pchet section possibly contains original research. Up to ring buffers can be used. Once all the control registers are set up, you set bit 0 of CSR0, and then wait for initialization to be done.
Of course, this precludes multicast support. At initialization, you would want the card to ‘own’ all the receive buffers so it can write new packets into pcney that it receives, then flip ownership to the driverand the driver to ‘own’ all the transmit buffers so it can write packets to be transmitted, then flip ownership to the driver.

Also I’m curious – on Win2K, where does vmtools get the adapter driver from?
